This invention relates` to steam boilers and .more particularly to asmoke consumer adapted. to be applied to a steam boiler of thelocomotive type and by means of which rsmoke and other products ofcombustion may wasA from the smoke box at the front of the iler and bereturned to the fire-box and consumed' therein. j

One object of the invention is to provide an attachment of the characterdescribed which may be readily applied to a locomotive of a conventionalconstruction without changing the construction of the locomotive andthereby allow locomotives now in use to be equi pcd with the improvedsmoke-consuming evice, i

Another object of the invention is to allow the engine to be operated inthe usual mann'erif the attachment should ,become inoperdesirable totemporarily discontinue its use. `Another obj ectofthe invention is tocause air to-be drawny from the smoke box into a manifoldconnectedtherewith and forming part of the. attachment. and therebyallow a draft to be formed which will cause the smoke and; otherproducts of'com-bustion to be withdrawn from, the smoke box of thelocomotive-and `delivered'- tothe fire-box for rebuzrni-ng and alsoprovide the necessary driftfinorder to' cause the lire in the fire-boxto burn. v The. invention is illustrated inthe accompanyi'ng drawings,wherein Figure- 1 is a view 'showing a locomotive in Y' Y, side:elevation and having the limproved -smokaconsum-ingjdevice appliedthereto,

The locomotive, which is indicated in general by the numeral 1, is ofy aconventional construction and includes the usual smoke box2, fire-box 3and boiler 4 through which the ues 5 extend with their forward endssecured in a head 6. The customary exhaust nozzle? has been shown in thesmoke box andv there has also been shown the usual partitions 8 and 9defining a smoke passage 10 through which smoke and cinders usually passin order to be ejected from the smoke box through the stack 11 above thenozzle 7. There has also been shown the usual screen 12 customarilyemployed to cause large cinders to be broken into iine particles beforeleaving the smoke box. Y l

The attachment constituting the subject- Vmatter of this 4inventionincludes a manifold 70 13 which is preferably rectangular in crosssection and is curved longitudinally," as shown in Figs. 2 and 3, sothat itmay t snugly against the under face; of the rear portion of thesmoke box where it is secured `by rivets or equivalent 'fasteners passedthrough :ianges lt projecting from the walls of the manifold. Thismanifold vhas communication with the smoke boxl through Y openings 15and these openings are normally l80 closed by spring-actuated lcheckValves 16 yieldably held closed by springs 17 c which draw themupwardly. twill thus be seen that the openings 15 will be normallyclosed but may be opened when the check valves 8,5 are moved downwardlyby a draft. A gate 18 which extends transversely in the smoke box ispivotally mounted at one end, as shown at 19, and normally remains inavvlowered position in closing relation to the smoke pas- ,.907

sage 10. A cable 20 which` is secured to the.

extends outwardly through an opening in a side of the smoke box andisconnected with a pull rod 22 extending rearwardly along a side vot thelocomotive and into the cab 2,3 sothat the fireman or engineer can drawupon this rod to raise the gate if it is desired to have the locomotivefunction in the usual manner with the smoke and other products ef `@cntlsticn 9 livered from` the 'lire-box where they will be consumed. It

fold and causing the valves 16 Va quantity is attempting with the tankat jet of air may be bustionthrough the same in shape and of proper y,not only eliminates dangers of passing through the passage 10 and out ofthe smoke box through the stack 11. A screen 24 is )grovided in the rearportionA of the smoke ox above and to the rear of the openings 15 inorder to cause cinders passing from the lues 5 to be broken into fineparticles and thereby allowed topass through the attachment withoutbeing liable to clog the same.

Pipes 25 lead from the manifold 13 and are connected by a bridge plate26 from which extends a pipe 27 leading rearwardly and communicatingwith the casing 28 of a suction fan 29. This fan is operated by anelectric motor 30 `and when it is in operation it creates a suctionthrough the pipe 27, thereby establishing a suction in the manito bedrawn downwardly so as to uncover the openings 15 and allow smoke,cinders and other products offcombustion to be drawn from the smoke boxinstead of passing from the smoke box through the stack. This smoke andother products of combustion are forced from the `fan casing through apipe 31 to a distributor frame 32 which fits about thefire-box 3 of thelocomotive and a tank or large cylindrical chamber 3a is providedintermediate the length of the pipe 31 in order to allow smoke tocollect inthis chamber if too great to pass through the pipe at anytime. A pipeV 35 leading from a suitable source of air supplycommunicates its forward end so that a fed into, this tank and not only`assistpassage of the products of combut also supply air to the hre-box.i

The distributor frame 32 consists of pipe sections connected bycouplings in order to define a tubular frame which is rectangulardimensions to fit snugly about tlielire-box. A yoke 36 which is alsoformed of pipe extends upwardly from the distributor frame against therear wall y of the lire-box about the lire door 37 and from thisyoke andthe sideportions of the distributor frame extend nozzles 38 which passinto `the lire-box through its walls. By this arrangement smoke andcinders Iwill bededistributor" frame into the will thus be seenthatthesmoke and cinders instead of passing from ythe smoke box through thestack 11 may be returned to the lire-box where they will be consumed.This tires being caused by sparks but also prevents .danger of the traincrew orpassengers being injured by flying sparks. When-an engine isstanding still, the gate 18 may be opened and allow the products of"combustion to pass out 'through the stack" as the engine is notoperating under forced" draft g g and little or no smoke will becreated.
